`
`TITLE: CLOUD-BASED EMERGENCY LOCATION SERVICE
`
`Field
`
`[0001]
`
`The present disclosure relates to wireless devices, and more particularly to a system and
`
`method for enabling emergency location services.
`
`Description of the Related Art
`
`[0002] Wireless communication systems are rapidly growing in usage.
`
`In particular, cellular
`
`communication technology has become ubiquitous for telephony communication. One important
`
`use of cellular telephones is the ability to dial for assistance during an emergency.
`
`In many
`
`developed countries, emergency infrastructure exists such that an emergency call center is able to
`
`determine the location of a person making an emergency telephone call.
`
`[0003]
`
`In many developing countries, however, emergency location service infrastructure has
`
`not been established.
`
`In these countries, when a person dials an emergency helpline,
`
`the
`
`emergency call center may not have an effective way to determine the location of the caller.
`
`Most emergency callers now dial from mobile devices, and as a result the location cannot be
`
`reliably correlated with a particular telephone number (e.g., as was possible with landline
`
`phones). Improving the speed and accuracy with which an emergency call center is able to
`
`ascertain the location of a caller can be life-saving in many circumstances.
`
`[0004] Accordingly,
`
`improvements in emergency location service technology for wireless
`
`devices would be desirable.
`
`Summafl
`
`[0005]
`
`In light of the foregoing and other concerns, it would be desirable to provide a way for a
`
`wireless user equipment (UE) device with cellular communication capability to reliably and
`
`securely provide location information to an emergency call center.
`
`[0006] Accordingly, embodiments are presented herein of a method for a wireless UE device to
`
`utilize cloud service technology to facilitate the provision of location data to an emergency call
`
`center. The UE may include one or more radios (e.g.,
`
`including at least a cellular radio),
`
`including one or more antennas, for performing wireless communications. The UE device may
`
`also include a cellular modem. The UE device may also include a processing element configured
`
`to implement part or all of the method (e. g., by executing program instructions).
`
`In addition, the
`
`

`

`WO 2018/118026
`
`PCT/US2016/067832
`
`UE device may include a non-transitory computer accessible memory medium, which may store
`
`program instructions executable by the UE.
`
`In addition, the UE may communicate with a server
`
`that receives and stores location information of the UE, wherein the server may be a part of a
`
`cloud—based infrastructure that provides cloud—based services to the UE.
`
`[0007] According to some embodiments, the wireless UE may provide signaling to initiate an
`
`outgoing telephone call to an emergency call center.
`
`In other words, the user may dial an
`
`emergency number, such as 911 in the US, on his cell phone to make an emergency call,
`
`typically over a cellular network. A token may be provided during the signaling, wherein the
`
`token is associated with location information of the UE device stored on a server computer
`
`(referred to as a cloud server or location server).
`
`In some embodiments, the token may be
`
`encapsulated in a calling party sub—address field of the outgoing telephone call.
`
`In other
`
`embodiments, the token may be transmitted by the UE to the call center using a user—to—user
`
`signal supplementary service. The token may uniquely identify the UE device and/or may
`
`uniquely identify a user cloud service account associated with the UE device. The use of the
`
`token may provide for enhanced security, e. g., to prevent spoofing of the UE phone number.
`
`[0008]
`
`In some embodiments,
`
`the UE may request the token from a server (e.g., a cloud
`
`server), possibly in response to the emergency call being initiated, and in response to this request
`
`the server may generate and provide the token to the UE. The UE may also provide its location
`
`information (the location of the UE) to the server, also possibly in response to the emergency call
`
`being initiated, and the server may associate this location information with the token.
`
`In this
`
`manner, the token may be configured for use by the emergency call center to retrieve the location
`
`information of the UE device from the server computer. The UE device may also be configured
`
`to periodically provide location information updates to the server computer during the outgoing
`
`emergency telephone call to the emergency call center.
`
`[0009] When the call center receives the incoming emergency call from the UE device, the call
`
`center may receive the token from the UE device, wherein the token is associated with location
`
`information of the UE device stored on the server computer as previously described. The call
`
`center may then request / receive the location information from the server using the token. The
`
`received location information is useable to determine a location of the UE device from which the
`
`incoming emergency call was received, and the call center may then tranth the location of the
`
`UE device to an emergency responder, or perform another action, as appropriate. The received
`
`location information may be displayed on a display device, e.g., in a map.
`
`In one embodiment,
`
`

`

`WO 2018/118026
`
`PCT/US2016/067832
`
`the emergency call center may create a uniform resource locator comprising the token, wherein
`
`the URL specifies a webpage (maintained on or by the cloud server) configured to display a map
`
`including the location information.
`
`[0010] In some embodiments, where the respective country supports an emergency location
`
`service similar to the Advance Mobile Location (AML) standard, a mobile location server may
`
`be interposed between the emergency call center and the cloud server.
`
`In these embodiments, the
`
`emergency call center may request the location information using the token by providing the
`
`token to a mobile location server for provision to the cloud server. The location information may
`
`then be provided from the cloud server through the mobile location server to the call center.
`
`[0011] As noted above, the cloud server (also called the location server) may store location
`
`information received from the UE device. Upon receipt of a request from the UE, such as when
`
`the UE initiates an emergency call, the cloud server may generate and store a token associated
`
`with a user equipment (UE) device, wherein the token identifies the UE device. The cloud server
`
`may further provide the token to the UE device for provision in the telephone call to the call
`
`center as described above. As previously discussed, the cloud server may receive the token from
`
`the call center in response to the UE device making the emergency telephone call to the call
`
`center, and in response provide the location information to the call center in response to the
`
`received token from the call center. As mentioned above, in providing the location information
`
`to the call center, the server may generate a webpage including a map containing the location
`
`information, wherein the webpage is accessible to the call center upon receipt of a URL
`
`containing the associated token.

`
`Detailed Description of the Embodiments
`
`
`Terms
`
`[0024] The following is a glossary of terms used in the present disclosure:
`
`[0025] Memory Medium — Any of various types of memory devices or storage devices. The
`
`term “memory medium” is intended to include an installation medium, e.g., a CD-ROM, floppy
`
`disks, or tape device; a computer system memory or random access memory such as DRAM,
`
`

`

`WO 2018/118026
`
`PCT/US2016/067832
`
`DDR RAM, SRAM, EDO RAM, Rambus RAM, etc., a non-volatile memory such as a Flash,
`
`magnetic media, e. g., a hard drive, or optical storage; registers, or other similar types of memory
`
`elements, etc. The memory medium may include other types of memory as well or combinations
`
`thereof.
`
`In addition, the memory medium may be located in a first computer system in which the
`
`programs are executed, or may be located in a second different computer system which connects
`
`to the first computer system over a network, such as the Internet.
`
`In the latter instance, the
`
`second computer system may provide program instructions to the first computer for execution.
`
`The term “memory medium” may include two or more memory mediums which may reside in
`
`different locations, e.g., in different computer systems that are connected over a network. The
`
`memory medium may store program instructions (e. g., embodied as computer programs) that
`
`may be executed by one or more processors.
`
`[0026] Carrier Medium , a memory medium as described above, as well as a physical
`
`transmission medium, such as a bus, network, and/or other physical transmission medium that
`
`conveys signals such as electrical, electromagnetic, or digital signals.
`
`[0027] Programmable Hardware Element - includes various hardware devices comprising
`
`multiple programmable function blocks connected via a programmable interconnect. Examples
`
`include FPGAs (Field Programmable Gate Arrays), PLDs (Programmable Logic Devices),
`
`FPOAs (Field Programmable Object Arrays), and CPLDs (Complex PLDs). The programmable
`
`function blocks may range from fine grained (combinatorial logic or look up tables) to coarse
`
`grained (arithmetic logic units or processor cores). A programmable hardware element may also
`
`be referred to as “reconfigurable logic.”
`
`[0028] Computer System — any of various types of computing or processing systems, including
`
`a personal computer system (PC), mainframe computer system, workstation, network appliance,
`
`Internet appliance, personal digital assistant (PDA), personal communication device, smart
`
`phone, television system, grid computing system, or other device or combinations of devices.
`
`In
`
`general,
`
`the term "computer system" can be broadly defined to encompass any device (or
`
`combination of devices) having at least one processor that executes instructions from a memory
`
`medium.
`
`[0029] User Equipment (UE) (or “UE Device”) — any of various types of computer systems
`
`devices that is mobile or portable and that performs wireless communications. Examples of UE
`
`devices include mobile telephones or smart phones (e. g., iPhoneTM, AndroidTM—based phones),
`
`portable gaming devices (e.g., Nintendo DSTM, PlayStation PortableTM, Gameboy AdvanceTM,
`
`

`

`WO 2018/118026
`
`PCT/US2016/067832
`
`iPhoneTM), laptops, wearable devices (e. g. smart watch, smart glasses), PDAs, portable Internet
`
`devices, music players, data storage devices, or other handheld devices, etc.
`
`In general, the term
`
`“”UE or “UE device” can be broadly defined to encompass any electronic, computing, and/or
`
`telecommunications device (or combination of devices) which is easily transported by a user and
`
`capable of wireless communication.
`
`[0030] Base Station — The term “Base Station” has the full breadth of its ordinary meaning, and
`
`at least includes a wireless communication station installed at a fixed location and used to
`
`communicate as part of a wireless telephone system or radio system.
`
`[0031] Processing Element — refers to various elements or combinations of elements.
`
`Processing elements include, for example, circuits such as an ASIC (Application Specific
`
`Integrated Circuit), portions or circuits of individual processor cores, entire processor cores,
`
`individual processors, programmable hardware devices such as a field programmable gate array
`
`(FPGA), and/or larger portions of systems that include multiple processors.
`
`[0032] Automatically — refers to an action or operation performed by a computer system (e. g,
`
`software executed by the computer system) or device (e.g., circuitry, programmable hardware
`
`elements, ASICs, etc), without user input directly specifying or performing the action or
`
`operation.
`
`Thus the term “automatically” is in contrast
`
`to an operation being manually
`
`performed or specified by the user, wherein the user provides input to directly perform the
`
`operation. An automatic procedure may be initiated by input provided by the user, but the
`
`subsequent actions that are performed “automatically” are not specified by the user, i.e., are not
`
`performed “manually,” wherein the user specifies each action to perform. For example, a user
`
`filling out an electronic form by selecting each field and providing input specifying information
`
`(e. g., by typing information, selecting check boxes, radio selections, etc.) is filling out the form
`
`manually, even though the computer system must update the form in response to the user actions.
`
`The form may be automatically filled out by the computer system where the computer system
`
`(e. g., software executing on the computer system) analyzes the fields of the form and fills in the
`
`form without any user input specifying the answers to the fields. As indicated above, the user
`
`may invoke the automatic filling of the form, but is not involved in the actual filling of the form
`
`(e. g, the user is not manually specifying answers to fields but rather they are being automatically
`
`completed).
`
`The present
`
`specification provides various examples of operations being
`
`automatically performed in response to actions the user has taken.

`Figure 1 — Communication System
`
`[0033]
`
`Figure 1
`
`illustrates
`
`an exemplary wireless communication system for enabling
`
`emergency location services, according to some embodiments.
`
`It is noted that the system of
`
`Figure 1 is merely one example of a possible system, and embodiments may be implemented in
`
`any of various systems, as desired.
`
`[0034] As shown, the exemplary wireless communication system includes a user equipment (UE)
`
`106 and a base station (BS) 102. The user device 106 may be referred to as a UE or UE device.
`
`The UE 106 may be a device with wireless (e.g., cellular) network connectivity such as a mobile
`
`phone, a hand-held device, a computer or a tablet, an accessory device, or virtually any type of
`
`wireless device.
`
`[0035] The base station 102 may provide cellular communication services to the UE 106. The
`
`base station 102 may be a base transceiver station (BTS) or cell site (a “cellular base station”),
`
`and may include hardware that enables wireless communication with UEs 106 according to one
`
`or more cellular communication protocols. The UE 106 and the cellular base station 102 may
`
`communicate using any of various cellular communication technologies such as GSM, UMTS
`
`(WCDMA), LTE, LTE-Advanced (LTE-A), 3GPP2 CDMA2000 (e.g., 1xRTT, 1xEV-DO,
`
`HRPD, eHRPD), etc,
`
`[0036] As shown, the cellular base station may be equipped to wirelessly communicate with a
`
`server 108 (e.g., a cloud platform which provides cloud-based services to UEs, one example
`
`being an iCloud platform, or another type of server). Thus, the base station 102 may facilitate
`
`communication between the UE 106 and the server 108.
`
`In particular, the cellular base station
`
`102 may provide the UE 106 with various telecommunication capabilities, such as voice and
`
`SMS services (e.g.,
`
`typically via circuit-switched wireless links) and/or data services (e.g.,
`
`typically via packet-switched wireless links).
`
`[0037] The BS 102 may be further equipped to wirelessly communicate with a call center 110
`
`(e.g., an emergency call center, a public-safety answering point (PSAP), or another type of call
`
`center). Thus, the base station 102 may facilitate communication between the UE 106 and the
`
`call center 110. The UE 106 may thereby be able to place a call (which may be an emergency
`
`call) to the call center 110 through the base station 102.
`
`[0038]
`
`The UE 106 may be capable of communicating using multiple wireless communication
`
`standards. For example, the UE 106 may be configured to communicate using at least one
`
`wireless networking (e. g, Wi-Fi) and/or peer-to-peer wireless communication protocol (e. g, BT,
`
`

`

`WO 2018/118026
`
`PCT/US2016/067832
`
`Wi-Fi peer-to-peer, etc.) and at least one cellular communication protocol (e.g., GSM, UMTS
`
`(WCDMA), LTE, LTE—Advanced (LTE—A), 3GPP2 CDMA2000 (e.g.,
`
`lxRTT,
`
`leV—DO,
`
`HRPD, eHRPD), etc.). The UE 106 may also or alternatively be configured to communicate
`
`using one or more global navigational satellite systems (GNSS, e.g., GPS or GLONASS), one or
`
`more mobile television broadcasting standards (e.g., ATSC-M/H or DVB-H), and/or any other
`
`wireless communication protocol, if desired. Other combinations of wireless communication
`
`standards (including more than two wireless communication standards) are also possible.
`
`[0039] The server 108 may be configured to communicate directly with the call center 110. For
`
`example,
`
`the server and the call center may both be connected to the Internet, and may be
`
`configured to communicate with each other through the Internet. The server and the call center
`
`may additionally be configured to communicate by some other wireless communication
`
`technology, such as a cellular communication protocol and/or other wireless communication
`
`protocols.
`
`Figure 2 — Exemplam Block Diagram of a UE
`
`[0040]
`
`Figure 2 illustrates an exemplary block diagram of a UE 106, according to some
`
`embodiments. The UE 106 may include a processor that is configured to execute program
`
`instructions stored in memory. The UE 106 may perform any of the methods embodiments
`
`described herein by executing such stored instructions. Alternatively, or in addition, the UE 106
`
`may include a programmable hardware element such as an FPGA (field—programmable gate
`
`array) that is configured to perform any of the method embodiments described herein, or any
`
`portion of any of the method embodiments described herein.
`
`[0041]
`
`The UE 106 may be configured to communicate using any of multiple wireless
`
`communication protocols. For example, the UE 106 may be configured to communicate using
`
`two or more of CDMA2000, LTE, LTE-A, Wi-Fi, or GNSS. Other combinations of wireless
`
`communication standards are also possible.
`
`[0042]
`
`The UE 106 may include one or more antennas for communicating using one or more
`
`wireless communication protocols. The UE 106 may share one or more parts of a receive and/or
`
`transmit chain between multiple wireless communication standards; for example, the UE 206
`
`might be configured to communicate using either of CDMA2000 (lxRTT / leV-DO / HRPD /
`
`eHRPD) or LTE using partially or entirely shared wireless communication circuitry (e. g., using a
`
`shared radio or at least shared radio components). The shared communication circuitry may

`
`include a single antenna, or may include multiple antennas (e.g., for MIMO) for performing
`
`wireless communications. Alternatively,
`
`the UE 106 may include separate transmit and/or
`
`receive chains (e.g., including separate antennas and other radio components) for each wireless
`
`communication protocol with which it is configured to communicate. As a further possibility,
`
`the UE 106 may include one or more radios or radio components which are shared between
`
`multiple wireless communication protocols, and one or more radios or radio components which
`
`are used exclusively by a single wireless communication protocol. For example, the UE 106
`
`might include a shared radio for communicating using either of LTE or CDMA2000 lxRTT, and
`
`separate radios for communicating using each of Wi-Fi and Bluetooth. Other configurations are
`
`also possible. The UE 106 may be configured to disable (e.g., to power down) the one or more
`
`radios and/or one or more radio components, for example to limit power consumption (such as
`
`during times of low device use).
`
`[0043] As shown, the UE 106 may include a system on chip (SOC) 200, which may include
`
`portions for various purposes. For example, as shown, the SOC 200 may include processor(s)
`
`202 which may execute program instructions for the UE 106 and display circuitry 204 which
`
`may perform graphics processing and provide display signals to the display 260.
`
`The
`
`processor(s) 202 may also be coupled to memory management unit (MMU) 240, which may be
`
`configured to receive addresses from the processor(s) 202 and translate those addresses to
`
`locations in memory (e.g., memory 206, read only memory (ROM) 250, Flash memory 210)
`
`and/or to other circuits or devices, such as the display circuitry 204, wireless communication
`
`circuitry 230 (also referred to as a “radio”), connector I/F 220, and/or display 260. The MMU
`
`240 may be configured to perform memory protection and page table translation or set up.
`
`In
`
`some embodiments, the MMU 240 may be included as a portion of the processor(s) 202.
`
`[0044] As shown, the SOC 200 may be coupled to various other circuits of the UE 106. For
`
`example, the UE 106 may include various types of memory (e.g., including NAND flash 210), a
`
`connector interface 220 (e.g., for coupling to a computer system, dock, charging station, etc), the
`
`display 260, and wireless communication circuitry (or “radio”) 230 (e.g., for LTE, LTE-A,
`
`CDMA2000, Bluetooth, Wi-Fi, GPS, etc.).
`
`[0045] As noted above, the UE 106 may be configured to communicate wirelessly using
`
`multiple wireless communication standards. As further noted above,
`
`in such instances,
`
`the
`
`wireless communication circuitry (radio(s)) 230 may include radio components which are shared
`
`between multiple wireless communication standards and/or
`
`radio components which are
`
`

`

`WO 2018/118026
`
`PCT/US2016/067832
`
`configured exclusively for use according to a single wireless communication standard. As
`
`shown, the UE device 106 may include at least one antenna (and possibly multiple antennas, e.g.,
`
`for MIMO and/or for implementing different wireless communication technologies, among
`
`various possibilities), for performing wireless communication with base stations, access points,
`
`and/or other devices. For example, the UE device 106 may use antenna 235 to perform the
`
`wireless communication.
`
`[0046]
`
`The UE 106 may also include and/or be configured for use with one or more user
`
`interface elements. The user interface elements may include any of various elements, such as
`
`display 260 (which may be a touchscreen display), a keyboard (which may be a discrete
`
`keyboard or may be implemented as part of a touchscreen display), a mouse, a microphone
`
`and/or speakers, one or more cameras, one or more buttons, and/or any of various other elements
`
`capable of providing information to a user and/or receiving/interpreting user input.
`
`[0047] As described herein, the UE 106 may include hardware and software components for
`
`implementing features for distributing a token to enable emergency location services. The
`
`processor 202 of the UE device 106 may be configured to implement part or all of the features
`
`described herein, e.g., by executing program instructions stored on a memory medium (e. g., a
`
`non-transitory computer-readable memory medium). Alternatively (or in addition), processor
`
`202 may be configured as a programmable hardware element, such as an FPGA (Field
`
`Programmable Gate Array), or
`
`as
`
`an ASIC (Application Specific Integrated Circuit).
`
`Alternatively (or in addition), the processor 202 of the UE device 106, in conjunction with one or
`
`more of the other components may be configured to implement part or all of the features
`
`described herein, such as the features described below.

`Figure 3 — Exemplam Block Diagram of a Base Station or Server
`
`[0048]
`
`Figure 3 illustrates an exemplary block diagram of a cellular base station (BS) 102 or a
`
`server 108, according to some embodiments. The descriptions below are made in reference to
`
`the base station 102, but it may be understood that similar configurations of components are also
`
`possible for the server 108. It is noted that the base station of Figure 3 is merely one example of a
`
`possible base station. As shown, the base station 102 may include processor(s) 304 which may
`
`execute program instructions for the base station 102. The processor(s) 304 may also be coupled
`
`to memory management unit (MMU) 540, which may be configured to receive addresses from
`
`10
`
`

`

`WO 2018/118026
`
`PCT/US2016/067832
`
`the processor(s) 304 and translate those addresses to locations in memory (e. g, memory 360 and
`
`read only memory (ROM) 350) or to other circuits or devices.
`
`[0049]
`
`The base station 102 may include at least one network port 370. The network port 370
`
`may be configured to couple to a telephone network and provide a plurality of devices, such as
`
`UE devices 106, access to the telephone network as described above in reference to Figure 1.
`
`[0050]
`
`The network port 370 (or an additional network port) may also or alternatively be
`
`configured to couple to a cellular network, e. g., a core network of a cellular service provider.
`
`The core network may provide mobility related services and/or other services to a plurality of
`
`devices, such as UE devices 106.
`
`In some cases, the network port 370 may couple to a telephone
`
`network via the core network, and/or the core network may provide a telephone network (e. g,
`
`among other UE devices serviced by the cellular service provider). The base station 102 may
`
`also be coupled to an Emergency Alert System (EAS) via the network port 370, by which means
`
`the base station may receive emergency alert messages to distribute to cellular devices via
`
`cellular broadcast.
`
`[0051]
`
`The base station 104 may include at least one antenna 334, and possibly multiple
`
`antennas. The at least one antenna 334 may be configured to operate as a wireless transceiver
`
`and may be further configured to communicate with UE devices 106 via radio 330. The antenna
`
`334 communicates with the radio 330 via communication chain 332. Communication chain 332
`
`may be a receive chain, a transmit chain or both. The radio 330 may be configured to
`
`communicate via various wireless telecommunication standards, including, but not limited to,
`
`LTE, WCDMA, CDMAZOOO, etc.
`
`[0052]
`
`The base station 102 may be configured to support provision by a UE 106 of messages
`
`received via cellular broadcast
`
`to other devices
`
`(e. g, devices without native cellular
`
`communication capabilities).
`
`In particular, as described further subsequently herein, the BS 102
`
`may include hardware and software components for implementing (or for use in conjunction with
`
`a UE 106 implementing) part or all of a method for a UE 106 to provide indications of messages
`
`received by the UE 106 by way of cellular broadcast techniques to another device.
